Helicoids are lubricated with grease. Then adding oil will likely result in a mess. Actually it would do so even with a dry helicoid. The oil would run where it should not.
Agree. It's the helicoid that should be cleaned and re-lubed. Putting oil just on the collar would be quite useless, and it may begrime the lenses and the shutter blades. Lubricating oils are amazingly capillary and get almost everywhere, if you just give them some time.
That's a wonderful idea! While you're at it, take the lens off the camera and give the mirror box a good shot of WD-40. Be sure to get plenty in around the shutter curtains. Opening the back and spraying the sprocket and takeup spool would be good, too.
Be sure to spray around the advance lever, shutter speed dial, rewind knob & shaft, shutter release, etc..

I would have thought that it was over-the-top stupid enough that it would be taken as sarcasm, especially since the first three posts gave excellent advice.

I've worked on many clocks and watches that got that treatment. WD- 40 is great stuff in many ways, but it's miserable to remove after the carrier evaporates and it dries up.
It seems that basic lubrication principles - "if it spins, oil; if it slides, grease" - something most any farmer understood in say 1960 have been replaced with "spray it with something"
The problems with the m16 rifle, due to inappropriate lubrication make interesting reading.

After MacNamara decided to spend the extra couple of bucks on the plated chamber, that solved a lot of problems.
I successfully fired three round with the M16 I had in VN, Never tried it again. Crew member in a Huey & used an M60 once in a while.
